AUXILIARY VISE AUTOMATIC.

. .Application filed April 7,

The invention is an attachment tor linotype, intertype or line casting machines which works in conjunction with the normal operation oi the machine and autov matically operates to stop the machine when using the high mold when the operator negy lects to utilize the first elevator slide filling piece. f

The object of the inventionis yto provide" an automatic safety stop which will notfinterfere' with the normal operation of the machine and which will Vautomaticallyv stop the machine when the first elevator travels i beyond the correct position. p n Another object of the'y invention is to provide means for constructing the vise 'auto- ,matic stopmold disc dog which will permit the lower halt' of the dog to slide to auto* maticallypoperate the safety device when the machine is operating normally Vwhile the upper halfremains stationary.

' A turtherobject of the invention to provide a slidable attachment on the Vvise` position, which is ofV a simple and economd 3 ical construction.

embodies asplit dog which will replace the vise automatic stop mold disc dog, a bar` slidably held on the vvist-i automatic stop rod, ya pin extending upward from the said bar and adaptable to engage the runder side Vof the vhead ot the elevator sliden a spring for resiliently holding the `bar upwarch` `and n ak clip that may be attached to the moldv disc" y Y a U-shapedband 1-0 which is placed around the "vise automatic stop rod which is indio .adjacent the mold opening.

Other features and advantages `ofthe invention will appear froml the following description taken in connection with the drawings herein:` z f.

Figure l is a sectional view through the first `elevator and mold of a linotype machine with parts omitted showing the device ready to use the high'mold with the first elevator slide in the upper position.

Figure 2 is a similar view showing the in the lower position before the disc- 'l lVith these ends in view the inventionV 1927. s eriai No. 181,634.

yhas moved toward the elevator and whenV the operator has failed to use the iirstelevat-or slide filling piece.

Figure 3 is a similar view showing v'the device in the normal operating position whenusing the lower mold.

Figure 4 is a detail showing a longitudinal section through the'vise automatic stop mold disc dog.

Figure 5 is a similar view showing the lower halt of the stop mold disc'dog as it is normally moved bythe mold onthe disc.

Figure 6` is a side view ofthe firstelevator with parts omitted which shows the position of `the, first elevatorslide filling piece. l.

ln the drawings the vdevice is shown as it would be made wherein numeral l indicates the vise automatic stop mold disc dog, nu-

:rneralQy the bar whichk is slidably held (on the vise automatic stop rod7 and numeral 3 areinovable clipthat is only used when the upper mold is being used. The disc dog l is made as shown in Figure a with an upper section fl and a lower` section 5 and afspring 6 yin a circular opening 7 'betweenthe twoV sections, It will' be noted that the upper sectionA isprovided rwith a projection 8 at one end thatk extends downward into the circular opening 7 vandfthe lower section 5 1s provided with a projection 9 that extends upward into the circular'opening T so that one end of the spring will engagek the projection 8. and the other the projection 9 which will Vcause the two members tobe resiliently held in the position shown and it will be observed that the lower section may move -to the position shown in dotted lines in vFigure -l whilethe upper section remains stationary. This dog` is slidably mountedy in the circular opening provided in theu Itrame for the visev automatic stop vmold'discdog.V f

The bar 2 is vertical and slidably held by cated: bythe numeral `lland at the upper end yot the bar 2 is alever lwhich is pivotally attached to it by a pin 13 and `which extends upward through the elevator trame which is indicated by the numeral lei. to a point l5 so that it will engage. the under side of the first elevator slide head as it moves downward. The lever l2 is provided with a spring 16, which is attachedto an eye l? on the under side ci? the frame 1.4i to lio resiliently hold the lever and bar 2 in the upper position shown in Figure l. It will be understood that any other suitable means may be used tor slidably mounting the bar Q, tor moving it downward when the elevator slide moves beyond the correct position, and lor rcsiiiently holding it upward.

The clip 3 may be readily attached to the disc adjacent the mold when using the upper mold and it will be observed that it will engage the upper portion of the dog l and thereby force the dog vagainst the lower end of the bar 2 when the operator has neglected to throw the Filling piece into place as indicated by the numeral 18, and the head of the elevator slide has moved downward beyond the correct position. It will be noted in Figure 5 that the Filling piece I8 is pivotally mountedv on the first elevator trame at the point 19 aud when the upper mold is being used it is thrown over from the position shown in full lines to the position shown in dotted lines so that it will engage the under side ofthe upper end of the first elevator slide.

It will be noted that in the normal operation of the machine a screw as indicated y the numeral 2O and loca-ted in the upper Vend of the elevator slide engages a pin 21 at the upper end ot the vise automatic stop rod 1l and Yforces this rod downward so that a projection 22 will pass below the under side o'l the dog l and permit the dog to move outward'to the position shown in Figure 3; however when the iirst elevator slide fails to move downward to the proper position the pin 2l is not moved downwardV so that the dog l will engage the projection 22 and prevent the mold disc moving over so that the machine will stop. This new device operates to stop the machine when the elevator slide moves downward too far when the upper mold is being used as when-the slide moves downward to such a position it nieves the bar 2 downward with the clip 3 in place the clip 3 will force the Vdog l against the bar 2 and stop the machine.

It will be understood that changes may be made in the construction without departing from the spirit ot the invention, one oi'fV which changes may be in the designor arrangement of the dog l, another may be in the use of other means for supporting the bar 2 or in the use ol a bar of another de-` sign, and still another may be in the use of other means to engage the upper `halif of the dog l instead of the clip 3.`

Y The construction will be readily understood trom the foregoing description. To use the' device t-he dog l and the bar 2 may be readily attached to orbuilt into the machineand may remain. in place while the machine is being used to operate with either the upper-or lower mold. `When using the upper mold the clip 3 may be attached to the disc and it will be observed that it will function to stop the machine when the lirst elevator slide moves beyond the correct position.

Having thus fully described the invention what I claim as new and desire tosecure by Letters Patent, is:

l. In a device oit the class described, a split dog with both members resiliently held endwise, said dog being adaptable to replace the vise automatic stop mold disc dog of a casting machine, a clamp adaptable to be attached to the mold disc to engage the upper portion of the said dog, a bar slidable on the vise automatic stop' rod, means for moving the said bar. downward to engage the upper portion of the said dog kwhen the first elevator slide fails to stop at the correct position and means for resiliently holding thesaid bar upward.

2. In a device of the class described, a split dog, means for resilient-ly holding the sections, one ofthe said sections being adaptable to be engaged by the mold on the mold disc, removable means tor engaging the other of the said sections, a bar slidably mounted on the stop rod and 'adaptable to be engaged by one of the sections of the said dog, and suitable means for' operating the said bar as desired,

3. In a device of the class described, a split pin adaptablev to replace the vise automatic stop mold disc dog oit a casting machine, one section of the said pin being adaptable to be engaged by the mold on the said mold disc, a clip on the saidmold disc for engaging the other of the saidA sections and means for engaging the opposite end of the said pin to 'stop the operation of the machine as desired. l y

t. In avdevice of the class described, a

Vresiliently held split pin adaptable to replace the stop dog oi a.' line casting machine, said pin adaptable to permit themachine to operatev normally, and means adaptableto engage the said pin to stop the operation of the said machine when the elevator slide fails to stop at a correctposition.

In testimony whereof I atix my signature.
